Web3 & Decentralized Application (dApp) Development

The emergence of Web3 represents the next major paradigm shift in the internet’s evolution — moving from centralized, platform-driven ecosystems to decentralized, user-controlled digital economies. This 5-day enterprise training program provides a deep dive into Web3 technologies, decentralized architectures, and the development of decentralized applications (dApps). Participants will learn how to build secure, scalable, and user-friendly dApps that integrate blockchain, smart contracts, and decentralized storage. The training blends foundational Web3 concepts with advanced hands-on development using tools such as Solidity, React, Ethers.js, and IPFS. By the end of this program, participants will have the ability to design and deploy fully functional dApps for real-world use cases across finance, supply chain, and digital identity.

Objectives of the Training

Understand the principles, components, and architecture of Web3 ecosystems.
Learn smart contract development using Solidity and deploy on Ethereum-compatible networks.
Gain hands-on experience integrating blockchain backends with front-end interfaces using Web3.js and Ethers.js.
Implement decentralized storage, APIs, and identity management using IPFS and ENS.
Design and deploy secure, scalable decentralized applications with wallet integration.
Understand the enterprise implications of Web3 technologies for digital transformation.
